This is something I made Linnea a while ago, when I was on a 1838-1840 kick. I'm aware that this is painfully specific, but I was intrigued by the sleeves that were in vogue at the time. The bodice decorations can be fascinating too.
This is the second dress of this time period I made. The first dress didn't have the delightfully puffy sleeves I was hoping for, so I hoped to make up for it in this one. The sleeves are cut into four pieces, tight upper sleeves, a cuff, big full lower sleeves and a ruffle to hide the join. It backfired a little in that the lower sleeves are too long and collapse upon themselves. Not the sort of look I wanted. Oh well.
The bodice has dropped shoulder and six pieces, with center back and side back pieces, and two parts in front. For this I added a box pleated ruffle. The skirt is plain and fluffs out wonderfully.
Beneath is a petticoat of plain white mystery fabric filled out with gathered panels of lace. By now I am fairly certain that tiered ruffled petticoats weren't period to this time, but it does the job well.
